Started well in which a delusional man, Gary Lambert (Brian Markinson), who believes his boss, Greg Pincus (John Apicella), may be a monster-and decides to take an entire office building, including Mulder, hostage to prove it. I like that but the man dies. The episode reminds me on episode "Duane Barry" the second season. Roger Cross from First Wave as Joshua stsrs in this episode as Agent Rice. It started well but then it felt rushed to me and it sucked because no one belived Mulder about the mosnter he sees everyone thinks he is paranoid and that he is not fit to be an F.B.I. agent anymore that is horrible. I hated the monster they create in her, it looked like a copy of the fly from David Cronenberg's masterpiece "The Fly. (1986)."
They should have made a movie about this monster episode but they never did. It was a monster movie called They Live (1989) John Carpenter's before this episode come out. Folie a Deux is a good last stand up alone horror episode just my at least favorite episode and I just don't care. I like the half of the episode the hostage situation and the girl employe of VinylRight corporation. I like Cynthia Preston as Nancy Aaronson and when she stairs at Mulder in Gary Lambert house is creepy I like that. Bu than episode turns in to boredroom.
Folie a Deux not my favorite episode but also not the worst one in The X-Files.
